Well... i was bored, so i entered major cities close to the four corners of the nation Takes 5 days, 6 hours of straight driving to make it.... (with tolls and no traffic) well... if you decide to take the scenic route, you're going to have to add an additional 3 days.... now in terms of gas used, i get about 300 miles per tank (highway), and about $30/tank so.... about 28.2 tanks of gas costing about $846.00 thats for the highways... if i did the scenic route it would be 29.8467 tanks costing me just a little more at about $895.40 now im using my car's highway mileage for this.. i suspect it would be a few more thanks on the scenic route...
